You need a lot of water when you're crushing multiple peaks in a single day. Stay hydrated while you ascend epic peaks and cross knife thin ridges with the help of the Nathan Men's Elevation Running Vest. Its vest like fit is less cumbersome and bulky than a regular backpack, and an included two liter reservoir keeps water within easy reach. The 3 Way Propulsion Harness system stabilizes up and down and side to side movement for a bounce free ride, and wall mesh shoulder straps and a perforated back panel help you stay cool underneath. Trekking pole clips hold your walking sticks when you're on mellower terrain. Multiple pockets and compartments keep snacks, gels, electronics, sunglasses, and other small items organized, and two water bottle pockets store extra reserves of precious fluid.
